We are doing something similar and using Cisco’s BNG on an ASR9k. We dont do dedicated CVLAN per sub on an AP, but we do a dedicated SVLAN per AP, and client isolate on the AP. That SVLAN is MPLS’d back to our BNG routers at the datacenters, so we’re in effect bridging that SVLAN across a routed MPLS network. Works great so you dont have to worry about tower IP pools filling up or being unused. One big pool at the BNG to rule them all.
On Cisco’s BNG each user does show up as its own sub-interface with radius capabilities of applying custom filters, rates, routes, etc per subscriber session. > On Jun 18, 2021, at 11:33 AM, D.
